A new world record for quantum teleportation has been set, bringing quantum communication networks that can stretch between cities a step closer. Two independent teams have transferred quantum information over several kilometres of fibre optic networks.
Being able to establish teleportation over long distances is a crucial step towards exchanging quantum cryptographic keys needed for encoding data sent over the fibres.
In a press conference on Wednesday, Chinese officials appear to have confirmed what many observers have long suspected: that China is no longer in control of its space station.
China's Tiangong-1 space station has been orbiting the planet for about 5 years now, but recently it was decommissioned and the Chinese astronauts returned to the surface. In a press conference last week, China announced that the space station would be falling back to earth at some point in late 2017.
Anyone who’s lived in a smoggy city would likely welcome the idea of using widely dispersed air filters to soak up all those toxic tidbits floating around—unless, of course, those filters were functioning human brains.
It’s good news for those equally at home on a treadmill or at a bar. Regular exercise seems to cancel out some of the risk of death that is linked to alcohol.
High alcohol intake is associated with fatal heart disease, stroke, and at least seven types of cancer.
An analysis of people over the age of 40 has found that people who do the recommended amount of physical activity a week – 150 minutes of aerobic exercising – but drink more than the UK weekly recommended limit are less likely to die than people who drink the same amount but exercise less.
There’s finally some progress in the fight against Zika. A vaccine is being given to 160 people in Zika-hit Puerto Rico, and a preliminary study has identified two existing drugs that seem to protect human brain cells from the virus.
The vaccine, developed by Inovio Pharmaceuticals, contains a synthetic DNA fragment similar to one in the virus itself. The company hopes that people who receive it will develop immune protection against Zika.
